DESCRIPTION

This command is used to modify cluster level settings. It allows users to change
the Couchbase root username and password, change the port that the cluster
manager listens on, and modify the data, index, and full-text service memory
quotas.

OPTIONS

-c

--cluster

Specfies the hostname of a node in the cluster. See the HOST FORMATS
section for more information on specifying a hostname.

-u

--user <username>

Specifies the username of the user executing the command. If you do not have
a user account with permision to execute the command then it will fail with
an unauthorized error.

-p

--password <password>

Specifies the password of the user executing the command. If you do not have
a user account with permision to execute the command then it will fail with
an unauthorized error. If this argument is specified, but no password is
given then the command will prompt the user for a password through
non-echoed stdin. You may also specify your password by using the
environment variable CB_REST_PASSWORD.

--cluster-username

Specifies the new username for the Couchbase administrator user.

--cluster-password

Specifies the new password for the Couchbase administrator user.

--cluster-ramsize

Specifies the data services memory quota. This quota will be assigned to all
future nodes added to the cluster with the data service.

--cluster-fts-ramsize

Sets the full-text service memory quota. This parameter is required if the
full-text service is specified in the --services option. This quota will be
assigned to all future nodes added to the cluster with the full-text
service.

--cluster-index-ramsize

Sets the index service memory quota. This parameter is required if the index
service is specified in the --services option. This quota will be assigned
to all future nodes added to the cluster with the index service.

--cluster-name

Sets the name for this cluster. Naming clusters is useful when you have
multiple Couchbase clusters in your deployment.

--cluster-port

Specifies the port for the Couchbase Administration Console. Defaults to
port 8091.

HOST FORMATS

When specifying a host for the couchbase-cli command the following formats are expected:

couchbase://<addr>

<addr>:<port>

http://<addr>:<port>

It is recommended to use the couchbase://<addr> format for standard
installations. The other two formats allow an option to take a port number which
is needed for non-default installations where the admin port has been set up on
a port other that 8091.

EXAMPLES

To change the username and password of the Couchbase administrator user run the
following command.

All of the parameters in this command can be specified at the same time. To
change the username and password of the Couchbase administrator user, change the
port number to 5000, change the cluster name to "new_name", change the memory
quota of the data service to 2048 and change the memory quota of the index
service to 4096 run the following command.

ENVIRONMENT AND CONFIGURATION VARIABLES

CB_REST_PASSWORD
